it's the thing they do where they take the costume/outfit the girls wore and put them into goods so you own a piece of the fabric they wore.
i never really liked those.. although i own EriJunLin ones cuz i just bought everything grad-related and didn't even know what they were at the time lol. and i certainly wouldn't pay 1500yen for these, though i've paid more for goods i'm sure other people wouldn't pay that much for.
I think it's a cute idea. I just got Haruna's costume card from Hellostore and am planning to get this. It's kind of one of those weird goods that would be neat to add to your collection. YAJ has Junjun's grad dress fabric one but they're trying to sell it for 6000yen which is like good luck she was never THAT popular. It's been sitting there since I started using YAJ
Either they had help or all the girls in C-ute have a really good eye for design because those are some of the best member designed goods I've ever seen.
Airi's towel omg. The two Suu-sans standing up when worn around the neck. But yeah, generally those are all very nice towels. The shirts are more of a mess (Airi's excluded), but holy crap, Nakajima's says "PENTAGRAM" all girlie-childish. I always like to think of how these things would look out of context, and homg. That would be amazing.
